SPINNING SPINDLE.

Application filed June 2, 1925. Serial No. 34,305.

This invention relates to spinning spindles such as are generally usedin silk and cotton mills, and, broadly considered, has for 1ts principalobject and purpose to provide sunple and easily operated means forthrowing the spindle out of engagement with the driv ing wheel andquicklybringing the spindle to a complete stop so that the operator mayhave the free use of both hands in connecting up the end of the thread.

It is another and more particular ob ect of our invention to provide apivotallymounted lever having means to coact with the pivoted spindlecarrying arm whereby when the lever is moved in one direction thespindle is thrown out of engagement with the face of the driving wheel,and an adjustable brake means carried by said lever and adapted toautomatically engage the rotating spindle as the latter is moved awayfrom the driving wheel whereby said spindle is quickly brought to acomplete stop'.

It is also a further object of our present improvements to provide anovel mounting of the spindle releasing lever and a simple and effectivelatch means therefor to retain said lever in its release position.

\Vith the above and other objects in view, the invention consists in theimproved releasing device for spinning spindles, and in the form,proportion, and'relative arrangement of the several parts thereof aswill be hereinafter more fully described, illustrated in theaccompanying drawings, and subsequently incorporated in the subjoinedclaims.

In the drawings, wherein we. have shown one simple andsatisfactoryembodiment of the invention, and in which similar referencecharacters designate corresponding parts throughout the several views,--Figure 1 is a side elevation illustrating one embodiment of our presentimprovements;

Fig 2 is a front view thereof;

Fig. 3 is a plan view, the spindle being shown in section and inengagement with the driving wheel, and

Fig. f is a similar view but showing the relative position of the partsafter the spindle has been disengaged from the driving wheel. I

For the purpose of illustrating one application ofour inventiomin theaccompanying drawings we have shown a pair of vertically spaced,horizontally positioned rails 5 which extend along the front of themachine and upon which the spaced spindle supports are mounted. stance,we have shown these rails as of cylindrical form and each of the spindlesupports includes a pair of plates 6 and 7,

In the present in respectively, which are provided in their 7 opposedfaces with concave seats to receive the rails 5. Between said railsthese plates are connected with each other by means of the bolt 8whereby they are rigidly clamped upon the rails.

The plate 6 at is upper end is formed with a laterally projecting arm 9upon which the angular spindle carrying bracket 10 is pivotally mountedat one of its ends, as at 11. The spindle 12, which is rotatablysupported in the other end of this bracket may be of any conventionaltype and is provided with a cylindrically enlarged section 13 forcontact with the facing 15 on the driving wheel 14, said facingpreferably consisting of leather or other suitable material of lightfrictional character. 7

The plate 7 is provided at its upper end with a horizontally projectinglug 16 upon which the lever 17 is supported intermediate of its ends forfree pivotal movement about a bolt 18 threaded or otherwise fixed insaid lug. Between the head of said bolt and the lever 17 a coilspringlt) is interposed. One end of the lever .17 is provided with adownwardly projecting finger 20 positioned against one side of thespindle carrying arm 10 at the upper end thereof and adjacent to itspivot 11. I j

At the opposite side of the pivot bolt 18 with respect to the finger 20,the lever 17 has a tooth 21 formed on the under side thereof adapted formovement over a series of rack teeth 23 formed upon the end of a lateralextension 22 on the upper end of the plate 7. By this means the lever 17is held againsta casual pivotal movement on the bolt 18, the spring 19acting upon said lever to maintain its tooth 21 in engagement with theteeth of the rack 23 but readily yielding so that said tooth 21 may moveover the rack upon the application of lateral pressure against the endof the lever.

The end of the lever 17 which is provided with the finger 20 also hasa'pin or stud- 2i projecting upwardly therefrom. This pin is loosely enggaged in an opening formed in an arm engaged upon the upper side of thele er 17. This arm at one end is formed with an obliquely inclinedcurved section 26 extending over the driving wheel l t and located atone side of the spindle 12. The end of this curved section 26 of the armprovided with a suitably formed holder for a brake shoe 2? of a suitablefrictional material.

The inner end of the arm 25 is provided with a slot 28 extending atright angles to the axis of said arm, said slot receiving a screw 20which threaded in the lever 17. By means of this screw 29, the arm 25may be securely clamped in an adjusted position upon the end of thelever whereby the brake shoe 2? may be caused to properly bear upon thespindle with the described frictional pressure.

Having above described the several mechanical features of the device,its operation will be understood as follows. Assuming that the spindleis being driven by frictional contact of the facing leather 15 on thedriv ing wheel 14 with the part 13 of said spindle, and that it isdesired to release the spindle from such driving engagement with thewheel, this may be easily done by simply moving the outer end of thelever 17 to the left from the position shown in Fig. 3 of the drawings.The finger 20 on said lever is thus caused to bear against the pivotedarm 10 and swin said arm to the right, thereby carrying the part 13 ofthe spindle away from the driving face of the wheel 14. In this movementof the lever 17 the brake shoe 27 is automatically brought intofrictional bearing engagement against the part 13 of the spindle in themanner illustrated in Fig. 4 of the drawings, as it will be observedthat the arc of movement of the spindle is much shorter than that of thebrake shoe. Thus when the spindle reaches its disengaged position, it issimultaneously engaged by the brake shoe 27 so that the frictionalresistance oll'ered by said shoe quickly brings the rotating spindle toa complete stop. Thus, the operator may employ both of his hands inconnecting up the loose end of the thread and it is not necessary forhim to first stop the rotation of the spindle. After the connection hasbeen made, the lever is again moved to its former position as shown inFig. 3 and the spindle returned to its opcrative position in engagementwith the driving face of the wheel 14. If desired, it will be understoodthat a suitable spring may be provided acting upon the arm 10 tonormally hold the spindle in the latter position. However, in thepresent instance, the operator after connecting the thread, moves thespindle a m 10 by hand, and said arm being against the finger 20 on thelever shifts the lever over the raoh 28 against the action of the spring19.

From the foregoing description considered in connection with theaccompanying drawing, the several features of our pres nt improven'ientsand the advantages thereof in practical use will be readily understood.Thus, we have found that by means of such a device, a gain ofapproximately in the speed. with which such spinn' machines may beoperated can be attained. By means of our improvements, a singlespindle, or as many spindles as desired can be quickly thrown out ofoperation at any time, thereby reducing wear upon the} leather frictionsurface of the drive wheel or wheels and correspondingly reducing theexpense incident to the replacement of such friction surfaces andprolonging the life thereof. I

Nevertheless, itwill be apparent to those familiar with this that the d vice mi h alsobe incorporated in various other al native constructions, and wetherefore, rcserve the privilege of adopting all s legitimate changes inthe form, proportion and relative arrangement of it several par; as maybe fairly embodied within the spirit and scope of the invention claimed.
